According to the dictionary, stuffing is uncountable. It simply means flavored food which is placed inside a paste/pastry etc.
You might say five-kind-of-stuffing moon cake. But it is a bit clumsy. It is more common for people to say "a moon cake with 5 kinds of stuffing". It is just similar to "a roast beef with onions" in the menu.
